KILN FOR DRYING GRAIN.

, Specification of Letters Patent No. 5,638, dated June 20, 1848.

To all whom it may concern Be it known that I, JOHN H. TOWER, of Kirkland, in the county of Oneida and State of New York, have invented a new and Im proved Mode of Kiln-Drying Grain, and Particularly Indian Corn; and I do hereby declare that the following is a full and exact description thereof.

The nature of my invention consists in passing the grain in a peculiar manner through a revolving and heated cylinder Fig. 1, A, composed of separate square apartments or tubes A, A, A, made of sheet iron fourteen feet long.

The frame work consists of an iron shaft, Fig. 2, C, C, one and a half inches in diameter resting on its bearings, Fig. 1, D, D, forming the axle of and passing through four cast iron wheels, Fig. 2, O, O, O, O, placed thereon at equal distances from each other, thirteen inches in diameter, having projections, a, b, 0, cl, 6, on their outer edges one quarter of an inch thick, one inch wide and two inches from each other, and between which projections the sheet iron tubes are placed, Fig. 3, A, A, and'are thus kept one quarter of an inch apart. The tubes are confined to these wheels by bands of hoop iron, Fig. 1, B, and Fig. 5, B.

The feeding end is made of sheet iron, Fig. 1, F, in a proper form to receive a spout G, passing from A hopper Which contains the undried grain and feeds the same like a common bolt in a mill. This feeding end F, is elevated one inch for each foot in length of the cylinder and the grain after passing through the cylinder falls into a hopper H.

The cylinder, Fig. 1, A, A, is placed within a brick arch of which I, I, is the base of cording to the dampness of the grain. A

cylinder of the dimensions above described willdry from ten to fifteen bushels per hour, the quantity depending upon the dampness above mentioned. The principle is such, that the cylinder may be made of any size feguired, or several may be inclosed in one It is necessary in order to have the grain properly and thoroughly dried that each kenel of it should come into contact with the heated sheet iron tubes and this is rendered practicable by the large amount of surface on the inside of each tube to which the comparatively small quantity of grain which is in it at any one time, is exposed.

That I claim as my invention and desire to secure by Letters Patent is The method as above described of con structing the grain-drier; that is to say, arranging a series of tubes similar to those described, in a cylindrical form, to be operated by a revolving shaft in the manner hereinbefore described.
